During-the early part of th'e"di'stil1ation a quantity of. acid mixed with adark colored oilvisi discharged from-the pipe G-into'the fupne'lL attached tothe pipe 1?, contained in the cooling-trough ,L, which I keep filled with cold water, and thence into a receiver placed at theextremjjty, of -P, and atlthesame time acid and asmall portion ofoil are discharged by the pipe H from therpo'st condejnserll into-the spout mend thence intoareceiver. The pipe'N on the top of the condenser F allows the uncon; densable-igases togesoape during the process.

When about fifty gallons inalll of this mixture ot oil and acid'liaye-been obtained frouijtlie pipes H and G,ioil of abrown'ish red color,

but nearlyl'fi ee from acid isdischarged by f Barticiilar attention' must now be" paid to i the fi're,in:B,-in order 't-hat'thstream of oil whichfiows' from -G' maybe continued as regular'a's pnssiblefiay to the extent of twenty five g'allpns per hour. V If the fire is urged too t- I e pipe 'G,c and.auerysmall portion of acid strong,jrosin in'an undecomposed state will 'be distilled'over along with the .oil, which considerably injures the'subsequent operations. I lation may be known by the oil assuming a light greenish tin-t. The fire must then be withdrawn-fron1 .B,- and the, still allowed to cool for four hours. The plug is thenwithdrawn from the short pipe 0, No. 1, and the pitchy residuum will flow into any convenient vessel placed to receive it. The mixture of oil and acid produced at the commencement "of the operation is allowed to separate in the,

vessels-in which it has been received, and-the oil rising to thesurface of the acid is decanted and m'ixed with the. oil obtained during the remainder of the'distil-lation to be again introduced into the still fora secondoperation,

in the c'arly"stage "of which a portionof oil.

'it'may be run into any convenient receiver placed at the extremity of the pipe P. The process, as in the first case, must be discontinued when the green color makes its appearance in the, oil; time being allowed for cooling the apparatus as before. The pitchy.

residuum is to be discharged at O, the redistiyllation to be continued until the oil is of the desired purity;- p

I do not claim the particular form or description' of apparatus still, or retorts as set iorth in the drawings Nos. 1 What I; claim is?- V 1. The process or mode of producing the American oil, as setforth'in the above specification' and drawings.
